Ebook: Podman in Action: Secure, rootless containers for Kubernetes, microservices, and more

The next generation of containers is here. Learn Podman directly from its creator, discover its exceptional security features, and start managing rootless containers that integrate easily into your systems.

In Podman in Action you will learn how to:
• Build and run containers in rootless mode
• Develop and manage pods
• Use SystemD to oversee a container’s lifecycle
• Work with the Podman service via Python
• Keep your containers confined using Podman security features
• Manage containerized applications on edge devices

Podman in Action shows you how to deploy containerized applications on Linux, Windows, and MacOS systems using Podman. Written by Daniel Walsh, who leads the Red Hat Podman team, this book teaches you how to securely manage the entire application lifecycle without human intervention. You’ll quickly get to grips with Podman’s unique advantages over Docker, and learn how easy it is to migrate your Docker-based infrastructure. It also demonstrates how, with Podman, you can easily convert containerized applications into Kubernetes-based microservices.
